If this is the initial "Auto eth0" connection, that's actually read-only
because it's a fake Ethernet connection to preserve the ability to just
plug in a cable and get a DHCP connection when there isn't anything
defined anywhere (like on a Live CD).  It just happens that in the
snapshot that Ubuntu 8.10 ships, it wasn't made read-only yet.

The ideal case is that the distro ships with a system-settings plugin
that can write connections back out, and when you modify that auto
connection, it actually *does* get saved somewhere.  But at the time of
that snapshot I'm not sure the keyfile plugin was usable enough.

Yes, make a new Ethernet connection, set it up, save it, and the "Auto"
connection will go away, and the one you just made will be used instead.
